Abstract

The invention discloses a throttle valve body assembly of an electric injection motorcycle. The assembly comprises a throttle valve body; an intake hole body with an intake port is arranged on the throttle valve body; a butterfly valve is arranged in the intake hole body by a butterfly valve shaft; one end of the butterfly valve shaft is connected with a spiral spring fixed on the intake hole body by a fixing device, and the other end is connected with a throttle valve butterfly valve drive; a connecting hole is formed in one side of the throttle valve body; an ECU positioned beside the intake port is arranged in the connecting hole by a bolt, and is connected with an ECU socket; an exhaust port, a pressure sensor and a temperature sensor are arranged on the throttle valve body; the intake port and the exhaust port are respectively positioned on two sides of the throttle valve body; and the pressure sensor and the temperature sensor are connected with the ECU. The assembly directly cools the ECU through air of the intake port, is compact in structure and smaller in size, and can reduce the cost and improve the cooling effect.

Description

technical field [0001] The invention relates to an electric spray motorcycle throttle valve body, in particular to an electric spray motorcycle throttle valve body assembly with better cooling performance. Background technique [0002] EFI motorcycle is a new type of motorcycle. According to the load of the engine, the fuel injection nozzle is controlled by the microcomputer to inject fuel to the cylinders that need to work, and the cylinders that do not work do not supply fuel. Compared with traditional carburetor motorcycles, EFI motorcycles are fuel-efficient, and can save more than 20% of fuel compared with the same type of carburetor motorcycles; due to the realization of digital ignition and fuel injection functions, fuel consumption is reduced and emissions are improved. The carburetor car is environmentally friendly and directly meets the European No. 11 emission standard. At the same time, it also has the characteristics of easy start-up, and the idle speed is stabl...
